The Science and Lived Experience of ICDs in HCM
The Science and Lived Experience of ICDs in HCM Sep 28, 2026 2030 Dr. Rachel J. Lampert, MD, a cardiac electrophysiologist and professor of medicine at Yale School of Medicine, and patient advocate Hannah Keime of HeartCharged join Dr. John Fritzlen to discuss arrhythmias, sudden cardiac death, and life after receiving an implantable cardioverter-defibrillator (ICD) in hypertrophic cardiomyopathy (HCM). The conversation covers how often patients with HC
Long-Term Realities: Managing Disease Progression and ICD Selection in Young HCM Patients
Long-Term Realities: Managing Disease Progression and ICD Selection in Young HCM Patients Jun 2, 2026 1768 Patient advocates Hannah and Bethany Keime from HeartCharged sit down with Dr. John Fritzlen to discuss the long-term journey of living with hypertrophic cardiomyopathy (HCM). The conversation covers the progressive nature of the condition, including the onset of heart failure symptoms, atrial fibrillation, and myocardial remodeling over decades, as well as how advanced diagnostics like c
Reevaluating Beta Blockers: New Evidence in Non-Obstructive HCM Care
Reevaluating Beta Blockers: New Evidence in Non-Obstructive HCM Care May 5, 2026 1050 Dr. Florian Rader joins Dr. Louise Bjerregaard to discuss a groundbreaking randomized, double-blind, triple-crossover trial that challenges the long-standing "mantra" of using beta blockers as first-line therapy for non-obstructive hypertrophic cardiomyopathy (HCM). Dr. Bjerregaard explains how the study compared bisoprolol, verapamil, and placebo, revealing that bisoprolol actually resul
The Personalized Heart: Moving Beyond the 15mm Rule in HCM Diagnosis
The Personalized Heart: Moving Beyond the 15mm Rule in HCM Diagnosis Apr 24, 2026 1263 Dr. John Fritzlen sits down with Dr. Hunain Shiwani to discuss a paradigm shift in diagnosing hypertrophic cardiomyopathy (HCM). For 50 years, the medical community has relied on a static 15mm wall thickness threshold that fails to account for individual body size, age, and biological sex; a bias that often leaves female patients underdiagnosed. Dr. Shiwani details his team’s groundbreaki
The ODYSSEY Continues: Deep Diving into Non-Obstructive HCM Data
The ODYSSEY Continues: Deep Diving into Non-Obstructive HCM Data Apr 24, 2026 1401 Dr. James MacNamara welcomes Dr. Milind Desai from the Cleveland Clinic to dissect the results and implications of the ODYSSEY trial, the largest study ever conducted in hypertrophic cardiomyopathy (HCM). The trial investigated the use of mavacamten in patients with non-obstructive HCM, a population with significant unmet medical needs. While the study did not reach statistical significan
Bionic Tech and Shared Decisions: Exploring the Spectrum of ICD Care in HCM
Bionic Tech and Shared Decisions: Exploring the Spectrum of ICD Care in HCM Dec 22, 2025 1737 In this episode of In the Thick of It, Dr. John Fritzlen joins leading electrophysiologist Dr. Mark Link and Hannah and Bethany from Heart Charged to discuss the critical role of implantable cardioverter-defibrillators (ICDs) in managing hypertrophic cardiomyopathy. The group navigates the complex clinical landscape of ICD indications, including the importance of MRI findings and specific
Redefining the Standard: Insights from the MAPLE Trial in Obstructive HCM
Redefining the Standard: Insights from the MAPLE Trial in Obstructive HCM Dec 22, 2025 1020 In this episode of In the Thick of It, Dr. Floridian Rader and Dr. Ahmad Masri discuss the transformative results of the MAPLE trial, a head-to-head study comparing aficamten—a cardiac myosin inhibitor—to metoprolol in patients with symptomatic obstructive hypertrophic cardiomyopathy1. The trial utilized a rigorous "double-dummy" design to ensure blinding while testing both medications at
Decoding Refractory Symptoms: Advanced Diagnosis and Management in HCM
Decoding Refractory Symptoms: Advanced Diagnosis and Management in HCM Dec 22, 2025 1282 In this episode of In the Thick of It, Dr. Madeline Smoot talks with Dr. Alex McNamara to discuss the complexities of managing refractory symptoms in patients with hypertrophic cardiomyopathy (HCM). The conversation highlights the distinction between obstructive and non-obstructive symptoms, emphasizing the importance of provocative testing—such as cardiopulmonary exercise testing (CPET)
The "Neglected Middle": Redefining HCM Genetics with Intermediate Effect Variants
The "Neglected Middle": Redefining HCM Genetics with Intermediate Effect Variants Dec 22, 2025 1750 In this episode of In the Thick of It, genetic counselor Matthew Thomas sits down with Dr. Roddy Walsh and Dr. Juan Pablo Ochoa to discuss their groundbreaking research on the genetic architecture of Hypertrophic Cardiomyopathy (HCM). The conversation centers on "Intermediate Effect Variants" (IEVs)—genetic markers that fall between rare, high-impact Mendelian mutations and common, low-im
The Center of Excellence: Redefining Specialized Care in HCM
The Center of Excellence: Redefining Specialized Care in HCM Dec 22, 2025 1657 In this episode of In the Thick of It, Dr. Betty Raman interviews Dr. Srihari Naidu, Director of the Hypertrophic Cardiomyopathy Medical Center at Westchester Medical Center, to explore what truly defines a "Center of Excellence". Dr. Naidu shares how his philosophy has evolved from a structural focus on advanced imaging and surgical tools to a patient-centered approach that prioritizes i
Metabolic Modulation in Non-Obstructive HCM: Exploring the FORTITUDE Trial
Metabolic Modulation in Non-Obstructive HCM: Exploring the FORTITUDE Trial Dec 22, 2025 1228 In this episode of In the Thick of It, hosts Dr. Betty Raman and Dr. James MacNamara welcome Professor Martin Maron, Director of the Hypertrophic Cardiomyopathy Center at Lahey Hospital & Medical Center, to discuss the innovative FORTITUDE-HCM study. This Phase 2b trial focuses on the symptomatic non-obstructive HCM population—a group considered to have one of the greatest unmet treat
